PROCESS FOR MANUFACTURING FIBER-REINFORCED RESIN WIRE

摘要

This process for amnufacturing fibre-reinforcing resin wire was devloped for use of the wire as a tension member for optical communication. This process comprises the following four processes. (1) Forcing glass fibres to pass in a long axis direction, (2) impregnating the moving glass fibre with a resin (3) passing the resulting tension member through a heated moulding die, (4) passing the tension member through a setting zone while applying a twisting force. This process is specified in that during processes (3) and (4) fibres are subjected to a twisting force using a twisting tool and in that twisting is carried out between the twisting tool and the heated moulding die. The reinfocing fibre is specified to be glass fibre robing. After processes (1), (2) and (3) it is also proposed that another process can be carried out, namely, setting the resin completely and then passing it through a separately provided heating zone tow hich a twisting force is applied. In this case the temperature of the heating zone is set higher than the glass-transition point or melting point of the glass fibre.
